I am using ACM format for writing a paper. I use the following algorithm sample that is taken from this form. I want to add input and output before MyProcedure. I tried many ways but all fails. Can someone guide me? Thank you

To add input and output before MyProcedure a possibility is to add the text before \begin{algorithmic} with starred hspace \hspace*{}(see 6.3.3 Horizontal Space) and the indentation \algorithmicindent (see 4.1 Blocks and loops). LaTeX normally removes horizontal space at the beginning of a line, to preserve this space, use the starred version.
